Numerical Simulation Research on Influencing Factors of Dust Consistency in Drilling Tunnels and Its Utilization

摘要：

In order to grip the distribution discipline and influencing factors of dnst consistency, according to the specific features and observational data on the drivage working face, taking use of the gas-solid two-phase flow as its basic theory, this passage establishes a mathematical model of the dust movement on drivage working face and uses FLUENT to conduct a numerical simulation of it. After comparison, it turns out that the result of the numerical simulation is in line with the observational data on the working face, which proved the correctness of the authors mathematical model and numerical simulation. On this basis, rite author changed the parameters of the drivage working face in order to find a method of ventilation which can reduce the dust coneeutration on the drivage working face.
